218 EPILOBIACE^. 



3-angled, % line long. — Not reported north of Santa Barbara, but to be 

 expected in San Luis Obispo Co. if not in Monterey. The only very 

 near allies of this si^ecies, (E. crassiuscula and (E. augelorum, are Lower 

 Californian, and have sessile contorted capsules. 



4. (tAYOPHYTUM, a. Jussieu. Erect very slender diffusely branch- 

 ing annuals, with alternate linear entire leaves and axillary small white 

 or purplish flowers. Calyx-tube not prolonged above the ovary, the 

 4-parted deciduous limb reflexed. Petals 4. Stamens 8, the alternate 

 ones usually minute and sterile ; filaments filiform ; anthers subglobose, 

 fixed near the middle. Ovary oblong or linear, compressed, 2-celled ; 

 stigma capitate or clavate. Capsule membranaceous, clavate, 2-celled, 

 4-valved. Seeds few or many, in one row in each cell, smooth, naked, 

 mostly oblong. 



1. 0. rainosissimum, T. & G. Fl. i. 513 (1840). Glabrous, or the 

 inflorescence puberulent, erect, with spreading branches, 14 — ^H ft. high: 

 leaves 1 in. long or less : fl. % line long, mostly near the ends of the 

 branches : capsule 2 — 3 lines long, on pedicels of about the same length, 

 often deflexed, 3 — 5-seeded. — Common species of the Rocky Mts. and 

 Great Basin, reaching our borders in Mono and other eastern counties. 



2. Gr. diffiisum, T. & G. 1. c. Nearly glabrous, branching dichoto- 

 mously and widely, 1 — 3 ft. high : fl. 2 — 4 lines broad, white, fading 

 purplish : capsules l^ — % in. long, exceeding the pedicels, the cells 

 4 — 8-seeded. — The most common Californian species ; abundant at middle 

 elevations, in open pine and sequoia woods from Calaveras Co. southward. 



3. G. racemosuin, T. & G. 1. c. .514. Glabrous or canescent with a 

 short appressed pubescence, % — Ifg ft. high, the branches mostly simple 

 and elongated : fl. 3^ line long, axillary the whole length of the branches: 

 capsules linear, sessile or short-pedicelled, 8 — 10 lines long, oo -seeded : 

 seeds erect in the cells. — In Humboldt Co., and northward. 



4. G. lasiospermuin, Greene, Pittonia, ii. 164 (1891). Erect, very 

 slender, 1 — 2 ft. high, with numerous dichotomous branches ; glabrous 

 except a scant pubescence on the flower-buds : corolla 1^^ lines long, 

 rose-color, turning purple : capsules on capillary erect pedicels, torulose, 

 few-seeded : seeds canescent with an appressed silky pubescence. — 

 Known thus far only from the Coast Range in the northern part of San 

 Diego Co., but probably occurring within our limits. 



5. Gr. puinilnm, Wats. Proc. Am. Acad, xviii. 193 (1883). Near G. 

 racemosuin, but smaller and less branching, seldom 6 in. high, glabrous 

 or nearly so : fl. less than a line broad : capsule erect, short-pedicelled, 

 1^ in. long, the numerous seeds oblique in the cells. — Said to occur from 

 San Bernardino northward throughout the State.
